chopping the sierra steering rack
ed_crouch - 4/12/05 at 09:23 PM

Chaps,
I have a sierra rack with the alloy outer tube (I understand some of them were steel??), and want to shorten it.

Does anyone know of where I could get the lathe work and possibly the tigging done in the Hampshire/Surrey/Berkshire area??

Anyone know of a good machine shop??

Ta.

do you have too shorten rack if you chassis is wider??

Ed, dont know if this is near enough, "MRC Fabrications" near Chichester. Phone Mark on 01243775655, if he can't do it, he will almost certainly know somebody that can. ATB Ray.

Yup.

You then extend the track rods!

Cheers,

I shortened a steel one for Joel on here a while back. I took some pics but then lost them.

If you ask him he'll post a pic I would think. No need for tig, I made a pretty nice job with the mig. Sierra rack doesn't use oil (only grease) so no need to be oiltight. (and the sleeve is a press fit so when painted water can't get in either)

When you say you migged the ally together, I take it you used aluminium wire and funny gas??

Ed.
p.s. When I say "funny gas", I mean Argoshield heavy or something that Halfords wouldnt know about?!?

Don't bother welding the alloy ones together. Just press them into a sleeve. Once bolted onto the chassis it can't go anywhere.

sorry, misread the original question!

I used a steel sierra rack, quite common on the late sierras.

As andyharding says though, no need to weld really, press fit and loctite will be fine, the pinion end of the rack is the bit that takes the key stress.
